The pump sound pressure level has been updated to an Equivalent Continuous
Sound Level (LAeq) to meet the intent of ANSI S1.13-1971, CAGI-PNEUROP S5.1
using four microphone locations.
GENERAL DESCRIPTION
The 9:1 ratio is an expression of the relationship between the eec-
tive air motor area and the eective lower pump area. When 150 p.s.i.
(10.3 bar) of air pressure is supplied to the air motor, the lower pump
end will develop a maximum 1350 p.s.i. (93.1 bar) of uid pressure (at
no ow). As the uid control is opened, the ow rate will increase as
the air motor cycle rate increases to keep up with demand.
